Flat to rent in Gallus from the middle of August (Frankfurt)

Im going to sadly be leaving Germany in the middle August and therefore need to give up my flat, and also sell some of my furniture, mainly tables and chairs.

I live in a 50sqm flat in Gallus, on Gutenbergstrasse. Its on the ground floor and I pay a total of €620 a month including utility bills. The kitchen and bathroom are great, theres a lovely big bedroom and a huge living room. We also have a cellar for storage and a laundry room for your washing machine. Parking places are never a problem in my neighbourhood. My area is very quiet and a good mix of nationalities. All of our neighbours are friendly and we all know each other and socialise with each other.
